ABSTRACT

A computer-implemented tool for automated classification and interpretation of documents, such as life science documents supporting clinical trials, is configured to perform a combination of raw text, document construct, and image analyses to enhance classification accuracy by enabling a more comprehensive machine-based understanding of document content. The combination of analyses provides context for classification by leveraging relative spatial relationships among text and image elements, identifying characteristics and formatting of elements, and extracting additional metadata from the documents as compared to conventional automated classification tools.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. Ser. No. 16/289,729 filed Mar. 1, 2019, entitled, “AUTOMATED CLASSIFICATION AND INTERPRETATION OF LIFE SCIENCE DOCUMENTS”, which is incorporated herein by reference in its entirety.

BACKGROUND

Automated classification is typically utilized to effectively manage text, images, and unstructured information in documents. Also referred to as categorization, clustering, or text classification, automated classification generally enables documents to be divided and organized based on a set of predefined categories or classes for rapid and easy retrieval of information.

SUMMARY

A computer-implemented tool for automated classification and interpretation of documents, such as life science documents supporting clinical trials, is configured to perform a combination of text, document construct, and image analyses to enhance classification accuracy by enabling a more comprehensive machine-based understanding of document content. The combination of analyses provides context for classification by leveraging spatial relationships among text and image elements, identifying characteristics and formatting of elements, and extracting additional metadata from the documents as compared to conventional automated classification tools.

The text analysis identifies raw text and its general location in a document. Text sequence can be optionally tracked in some implementations. The document construct analysis provides the automated classification and interpretation tool with additional understanding of the document by identifying relevant context such as spatial construct information (e.g., position of images on a page, location of text in headers, footers, titles, use of rows and columns in tables, etc.) and formatting (e.g., bold, italics, font, text size, etc.). The document construct analysis may also maintain connections among document elements by tracking text that neighbors document elements on either side. The image analysis is directed to graphical content such as logos, diagrams, charts and tables, captions, and the like to extract additional context to further deepen the machine-based understanding of the document.

Although text analysis may be utilized alone with satisfactory results in some limited classification implementations, the construct and image analyses are ordinarily not configured to operate individually for document classification. However, the combination of the three analyses provides an improvement in classification accuracy by operating synergistically to assist in disambiguation between document classes which can be numerous and subtly distinct in some cases. The combination of analyses enables document classes to be differentiated by providing additional meaning using the identified relevant context. This enables document text that would otherwise be ambiguous to be effectively utilized for classification purposes.

In various illustrative examples, the automated classification and interpretation tool is configured to apply machine learning to an artificial intelligence (AI) engine that is trained with historical classified documents. The AI engine may be accessed by the tool or be incorporated in whole or part into the tool, and utilized to implement the combined text, document construct, and image analyses in whole or part. The analysis algorithms are subject to adjustments from a human operator through a user interface (UI) that is exposed on the automated classification and interpretation tool. The adjustments can be used to improve the automated document classification and interpretation and may be used as a machine learning input to improve performance of the classification and interpretation tool in general.

The computing device supporting the automated classification and interpretation tool can incorporate an image capture device such as a camera or scanner or be configured to interoperate with a discrete image capture device that is used to digitize life science documents. The tool can be operated in the field to apply the text, document construct, and image analyses to provide real-time classification feedback for the captured documents to the human operator. The real-time classification feedback may include suggested classification for the captured documents as well as associated metadata in some implementations. The operator can review the suggested document classification and metadata and provide approval or corrections through the UI. Corrections can be used as machine learning inputs to enhance the accuracy of the automated classification and interpretation tool.

The present computer-implemented automated classification and interpretation tool provides improvements in the underlying operation of the computing device on which it executes by providing for increased classification accuracy. More specifically, the utilization of a combination of raw text, document construct, and image analyses enables efficient utilization of processing cycles, memory requirements, and network bandwidth by improving the machine's knowledge depth to produce more accurate classification to thereby reduce a need to perform manual reclassification or discard inaccurate classification results. The automated classification and interpretation tool may further enhance the efficiency of the human-machine interface on the computing device because the tool more accurately classifies life science documents which improves the effectiveness of subsequent computer-assisted document searches and retrievals.

DETAILED DESCRIPTION

FIG. 1 shows an illustrative computing environment 100 in which a human operator 105 employs a computing device 110 that is configured to support a computer-implemented automated classification and interpretation tool 115. The tool may be implemented, for example, as a software application that executes on the computing device. In alternative implementations, the automated classification and interpretation tool may be implemented using hardware, firmware, or a combination thereof depending on the needs of a particular implementation of the present automated classification and interpretation of life science documents. The automated classification and interpretation tool can interface with, or incorporate directly, an artificial intelligence (AI) engine 120 that may be implemented, for example, using a neural or deep-learning network, expert system, or other suitable system that is configured for machine learning.

The computing device 110 comprises an electronic device such as a personal computer, server, handheld device, workstation, multimedia console, smartphone, tablet computer, laptop computer, or the like. In the discussion that follows, the use of the term “computing device” is intended to cover all electronic devices that perform some computing operations, whether they be implemented locally, remotely, or by a combination of local and remote operation.

The automated classification and interpretation tool 115 may be configured to optionally communicate over a network link 125 with a remote computing device, resource, or service 130. While this illustrative example employs processing at the local computing device 110 (as indicated by reference numeral 140), it is noted that other processing allocations and arrangements may also be utilized. For example, the automated classification and interpretation tool may be instantiated as a remote or cloud-based application. Various combinations of local processing 140 and remote processing (as indicated by reference numeral 150) can be implemented as appropriate for a given automated classification and interpretation tool implementation.

The communications network link 125 can be implemented using any of a variety of network types and network infrastructure in various combinations or sub-combinations including local-area networks (LANs), wide-area networks (WANs), cellular networks, satellite networks, IP (Internet-Protocol) networks such as Wi-Fi under IEEE 802.11 and Ethernet networks under IEEE 802.3, a public switched telephone network (PSTN), and/or short range networks such as Bluetooth® networks. Network infrastructure can be supported, for example, by mobile operators, enterprises, Internet service providers (ISPs), telephone service providers, data service providers, and the like. The communications network link 125 may utilize portions of the Internet (not shown) or include interfaces that support a connection to the Internet so that the computing device 110 can access data or content and/or render user experiences supported by the remote service provider and/or other service providers (not shown).

Various image capture devices 155 can be utilized in the computing environment to capture images of life science documents that are deconstructed as described below. The image capture devices can be standalone devices such as cameras or scanners or be incorporated into other computing devices 110. The image capture devices can be deployed locally or remotely. For example, images can be captured at a remote worksite and transmitted to the local computing device 110 or be transmitted to a cloud-based storage service and then accessed by the computing device over a network link. Alternatively, the computing device and image capture device may be co-located.

FIG. 2 shows an illustrative classification model 205 under which life science documents 160 may be classified as part of a trial master file (TMF) 215. The life science industry typically needs to comply with requirements of regulatory agencies in their oversight of the design, conduct, recording, and reporting of clinical trials. The TMF is examined by inspectors to demonstrate the compliance of the sponsor, trial monitor, and the investigators with applicable standards and regulatory requirements. The TMF is the collection of life science documents that typically permits evaluation of the compliance of the clinical trial and the quality produced. It is noted that the term “life science document” has general applicability to the documents that are typically collected in the TMF.

The TMF 215 is organized with different categories or classes of life science documents 220 . . . 225. In some implementations, various subclasses 230 and content 235 may also be included in the TMF or utilized in classification systems other than those which use a TMF. The TMF may be organized to include categories or classes as defined by the Drug Information Association (DIA) in some cases.

FIG. 3 shows illustrative details of the computer-implemented automated classification and interpretation tool 115 that executes on the computing device 110. The inputs to the tool include the life science documents 160 and the outputs from the tool include a class tag 330 and event tag 335 that are respectively applicable to each of the documents 160. The class tag identifies the class 220 . . . 225 (or subclass or content as appropriate) into which the life science is classified by operation of the tool. The event tag identifies objects in the documents that the tool interprets as having significance for events, actions, and/or triggers. For example, the event tag may identify document content that pertains to issues of safety, regulatory factors, data management, and other information that is associated with the content of the document.

The computer-implemented automated classification and interpretation tool 115 includes functionalities configured for document deconstruction 305, text analysis 310, document construct analysis 315, image analysis 320, and classification and interpretation analyses 325. The classification and interpretation analyses are supported by the classification model 205 and an interpretation model 340 which may be implemented as part of the tool 115 or be externally implemented as databases or resources on other computing devices.

Document deconstruction 305 includes converting the captured life science documents 160 to a digitized form that uses a standardized data structure across all documents that is expressed for example using XML (eXtensible Markup Language) or other suitable representation. The quality of the source materials may be expected to vary widely in typical implementations. Thus, the document deconstruction can apply various techniques to accommodate noise and unwanted artifacts during digitization to improve quality of the input to the automated classification and interpretation tool 115. In some cases, relevant descriptive information such as metadata can be collected for the input life science documents and stored. Such information may be used, for example, for TMF management and other purposes.

FIG. 4 shows illustrative data structures that are respectively associated with the text, document construct, and image analyses that are applied in combination during operation of the computer-implemented automated classification and interpretation tool 115. A life science document text structure 405 supports the text analysis 310 to enable raw text to be identified from the life science documents 160 (FIG. 1), typically without regard to sequence context (i.e., using a “bag of words” approach). However, text sequence can be tracked and utilized in some implementations of the tool.

A life science document base metadata structure 410 supports the document construct analysis 315 to enable utilization of document context such as spatial construct information for document elements (e.g., position of images on a page, location of text in headers, footers, titles, use of rows and columns in tables, etc.) and formatting (e.g., bold, italics, font, text size, etc.). The document construct analysis may also maintain connections among document elements by tracking text that neighbors document elements on either side. A document images structure 415 supports the image analysis 320 to enable graphical content such as logos, diagrams, charts and tables, captions, and the like to extract additional context to further deepen the machine-based understanding of the life science documents.

An illustrative example of an application of the text, document construct, and image analyses to life science documents is now presented. FIGS. 5 and 6 show illustrative life science documents that may be classified in a TMF. FIG. 5 shows an illustrative protocol synopsis 505 and FIG. 6 shows an illustrative informed assent form 605. Details that are not pertinent to the presentation of the example have been redacted from the life science documents 505 and 605. The documents in this example are classified differently under DIA guidance, however each document has similar text content including the word “study.” The discussion that follows illustrates how the present computer-implemented automated classification and interpretation tool and application of the combination of text, document construct, and image analyses enables the disambiguation and accurate classification of the documents.

As shown in FIG. 7, the text analysis 310 includes an analysis of the raw text without consideration of formatting (as indicated by reference numeral 705). As noted above, text sequence may be optionally utilized (710) to provide additional context in some implementations. Here, for example, the text analysis identifies the word “study” is included in the informed assent document 605.

As shown in FIG. 8, the document construct analysis 315 includes analyzing the relative spatial position of document elements (805) such as text and images. Element characteristics are also analyzed (810) including text font, size, and format (e.g., bold, italics, underline, subscript, superscript, etc.). Context connections may also be analyzed (815) using, for example, the “nearest neighbor” concept, by keeping the connected location of the element in relation to the text information occurring just before and just after. Such content connection allows for an understanding of the relevance of a document element (e.g. image) in relation to its position within the document.

In this example, the document construct analysis 315 identifies the word “study” in the protocol synopsis document 505 as being at the top of the first page of the document with a bold font. The document construct analysis 315 further identifies that the document construction includes the word being in a cell of a table with neighboring text of “Title of Study.” Such characteristics constitute metadata that provides additional context that enables the computer-implemented automated classification and interpretation tool to gain deeper understanding of the protocol synopsis document 505 to thereby disambiguate it from the informed assent document 605 (FIG. 6).

As shown in FIG. 9, the image analysis 320 includes analyzing images in the document to generate additional metadata to aid document classification and interpretation (905). Location of the images in the document may also be identified (910). In some implementations, image to text conversions may be applied (915) to create digitization of text elements that may be included in the images. In this example, the image analysis identifies a hand written “wet ink” signature 920 and date 925 to verify that the informed assent document is signed. In some cases, the signature and date can be converted to digital representations. The image analysis may also facilitate understanding of the graphical company logo 930 to enable further understanding of an entity that owns the document.

FIG. 10 is a flowchart showing an illustrative classification process that may be used as part of the classification and interpretation analyses 325 (FIG. 3). In step 1005, relevant pages of the life science document of interest are collected. Document identification (ID) is checked at step 1010. In step 1015, latent semantic analysis (LSA) is performed which may weight document characteristics (e.g., bold text, header location, logo, etc.) for relevance. The LSA results are collated into a non-parametric analysis of covariance (ANCOVA) in step 1020. A maximum likelihood estimate is performed in step 1025, and the document is classified in step 1030, for example to core DIA standards.

FIG. 11 shows illustrative manual adjustments 1105 to the various text, document construct, and image analyses operating on the computer-implemented automated classification and interpretation tool 115 (FIG. 1) that may be utilized as machine learning input 1110. In this example, the human operator 105 can perform a review 1115 of the class and event tags 330 and 335 that are output from the tool. The operator may adjust document classification that the automated classification and interpretation tool can analyze to make appropriate changes in the underlying automated analyses. Alternatively, the operator may directly adjust the analyses themselves to achieve a desired outcome. In some cases, the operator may perform multiple adjustment iterations to assist the machine learning process by specifying different classification outcomes, or by varying processing parameters with each iteration.

FIG. 12 shows illustrative real-time classification feedback 1205 provided by the automated classification and interpretation tool 115 to a human operator 105. In this example, the tool may be separately instantiated on a portable computing device 110 that includes an image capture device such as an integrated camera. The device 110 can thus be operated in a field location 1200 that is co-located, for example, with the life science document 160. Alternatively, the automated classification and interpretation tool may be partially supported by a computing device 110 that is located back at a home office or corporate enterprise and/or using a remote service 130 in a cloud-computing configuration that uses various network links 1210 and 1215 to establish communication and interoperability among the computing elements.

The automated classification and interpretation tool 115 can be operated in the field location 1200 to rapidly apply the text, document construct, and image analyses 310, 315, and 320 to provide real-time classification feedback 1205 for the captured documents to the human operator 105. The real-time classification feedback may include suggested classification for the captured documents as well as associated metadata in some implementations. The operator can review the suggested document classification and metadata and provide approval or corrections through the UI that is exposed on the tool. Corrections can be used as machine learning inputs 1110 to enhance the accuracy of the automated classification and interpretation tool.

FIGS. 13, 14, and 15 show illustrative methods for automated classification of life science documents. Unless specifically stated, methods or steps shown in the flowcharts and described in the accompanying text are not constrained to a particular order or sequence. In addition, some of the methods or steps thereof can occur or be performed concurrently and not all the methods or steps have to be performed in a given implementation depending on the requirements of such implementation and some methods or steps may be optionally utilized.

FIG. 13 is a flowchart of an illustrative method 1300 that may be performed by a computing device that supports the automated classification and interpretation tool 115 (FIG. 1). In step 1305, the device receives digitized representations of the life science documents, the digitized representations including document elements comprising one or more of text or image. In step 1310, the device performs text analysis of the digitized representations of the life science documents, the text analysis including identifying raw words in the text. In step 1315, the device performs construct analysis of the digitized representations of the life science documents, the construct analysis including identifying document context that describes characteristics of document elements and relative spatial positioning of document elements on pages of the life science documents. In step 1320, the device performs image analysis of the digitized representations of the life science documents, the image analysis including identifying images and processing the identified images to extract additional characteristics for document elements. In step 1325, the device collectively utilizes results of the text, construct, and image analyses to classify the life science documents into one or more predefined classes.

FIG. 14 is a flowchart of an illustrative method 1400 that may be performed by a computing device that supports the automated classification and interpretation tool 115 (FIG. 1). In step 1405, the device deconstructs one or more life science documents into a standardized data structure to generate document elements comprising images and digitized text as an input to the computer-implemented automated classification and interpretation tool. In step 1410, the device performs a combination of text, construct, and image analyses on the document elements to create context-based representations of the life science documents whereby spatial relationships among document elements are identified. In step 1415, the device extracts metadata that describes one or more of the document elements. In step 1420, the device utilizes the context-based representations and extracted metadata to assist classification of the life science documents into pre-defined classes.

FIG. 15 is a flowchart of an illustrative method 1500 that may be performed by a computing device that supports the automated classification and interpretation tool 115 (FIG. 1). In step 1505, the device identifies raw text in a digitized life science document. In step 1510, the device identifies construction of the digitized life science document to identify relative spatial locations of text and image elements in the digitized life science document. In step 1515, the device identifies images to extract text in digitized form. In step 1520, the device identifies characteristics of raw and extracted text. In step 1525, the device utilizes results of each of the identification steps in combination to generate metadata. In step 1530 the device classifies the life science document utilizing the generated metadata.
